And this is the answer I got from my Copy-Cat GPT Model.
The first formal definition of reinforcement learning was given by John Sutton and Robert J. F. Kelly in “Probabilistic Programming: An Introduction” (Sutton & Sutton, 1982).
The main idea of reinforcement learning is to find a balance between exploration and exploitation, and to do so by learning how to interact with the environment. In the context of reinforcement learning, an agent learns to maximize the cumulative reward, and the main goals of reinforcement learning are:
1. Finding the optimal action in order to maximize the cumulative reward.
2. Learning a model that approximates the environment by learning to solve a task.
3. Using the learned model to predict future states of the environment using a stochastic approximation.
In a game like poker, where the player needs to win at the end, the goal is to maximize the probability of winning. If we look at the problem, and if we make the assumption that the player already has a pretty good representation of the environment, then we can think of the best possible algorithm as learning to predict the best response to any given gamble.
The task is to learn a model that has sufficient information about the environment to make predictions about the future based on whatever data is available. This is how we learn to compete in a given game.
In the context of reinforcement learning, we are not concerned about learning a model, but instead we are trying to find an optimal action that maximizes the cumulative reward for the agent. This is similar to how the gambler’s fallacy is used to think about learning a model by learning it from the data, and then using that model to predict the future.
In the context of reinforcement learning, however, we are not looking at modelling the environment, but instead are given a task with one goal. We are given a single state that we can predict the next move based on the data available.
Another very important difference between supervised learning and reinforcement learning is that in reinforcement learning tasks, the agent is given a set of data to learn from, while in supervised learning the agent is given examples to use in the learning process.
There are many different variants of the problem of RL. For example, one common task which is useful in RL is to learn a policy that maximizes the expected return for the agent.
Here the goal is to learn a policy which is such that the agent’s optimal action will be to take the action with the highest expected return. Another task that is useful in RL is to learn to predict the next state based on the current state and action.
The main difference between supervised learning and reinforcement learning is in the way that we define the problem, and we learn in the context of reinforcement learning.
